It cost $0.50 to download an individual song and $4 to downlad an album. Jada has $15 to spend downloading music.
PART ONE:
EXAMPLE: individual songs, numbers of albums...
6,3
22,1
30,0
PART 2:
Create a graph to show a visual representation of the solutions for the answers to the problem above. With albums as the y axis and songs on the x axis. Upload a photo of your graph and with a short summary for your explanantion.
Answers
Answer:
Graph is attached below.
The graph illustrates the music that Jada may have downloaded with the $15 (s)he spent. The x-axis represents the number songs and the y-axis represents the number of albums. The data shows what combination of music she may have downloaded. The number of songs and albums have a negative correlation because if more money is spent on one variable, there is less money available to spend on the other.
Step-by-step explanation:
How to create a graph:
Using the data from part 1, plot the points (6, 3) (22, 1) and (30, 0) onto the graph. Label the x and y axis as the question asks. The axis should have arrows at the end. Include a title for the graph.
Do not connect the points because this indicates that all the space between the points are possible. Connecting the points includes decimal numbers and you can't buy part of a song or album, only a whole song or album.

find x and y
2x+3y=80
Answers
Answer:
x = 40 + -1.5y
Step-by-step explanation:
Simplifying
2x + 3y = 80
Solving
2x + 3y = 80
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3y' to each side of the equation.
2x + 3y + -3y = 80 + -3y
Combine like terms: 3y + -3y = 0
2x + 0 = 80 + -3y
2x = 80 + -3y
Divide each side by '2'.
x = 40 + -1.5y
Simplifying
x = 40 + -1.5y
Given the function f(x) = 4(x − 11) − 9, determine the value of x such that f(x) = -13.
Answers
Answer:
For x = 10, the value of the given function f(x)= 4(x − 11) − 9 is -13.
Step-by-step explanation:
Here, the given expression is:
f(x) = 4(x − 11) − 9
Now, given: f(x) = -13
⇒ -13 = 4(x − 11) − 9
Now, solving for the value of x, we get:
-13 = 4(x-11) -9
⇒ -13 = 4 x - 44 - 9
or, -13 + 44 + 9 = 4x
or, 4 x = 40
or, x = 40/4 = 10
or, x = 10
Hence, for x = 10, the value of the given function f(x)= 4(x − 11) − 9 is -13.

A company makes and sells headphones. The
function R= - 5x² +65x + 700 gives the amount
of money the company expects to make when the
price of the headphones is x dollars. When this
function is graphed, the vertex is 6.5, 911.25).
What does the x-value 6.5 represent?
Answers
Final answer:
The x-value 6.5 in the quadratic function's vertex represents the price of the headphones in dollars at which the company's expected revenue is maximized, according to the revenue function [tex]R= - 5x^2 +65x + 700[/tex].
Explanation:
The question involves understanding the meaning of the x-value in the vertex form of a quadratic function, which in this context represents the price of the headphones for which the company expects to make the maximum revenue. The given function is [tex]R= - 5x^2 +65x + 700[/tex], and the vertex of the graph of this function is given as (6.5, 911.25). The x-value, 6.5, therefore represents the price in dollars at which the revenue of the company is maximized. This is because, in the context of a quadratic revenue model, the vertex represents the maximum point when the parabola opens downwards (which it does, since the coefficient of x² is negative), meaning that increasing or decreasing the price from this point will lead to a decrease in the total revenue.

Answers
Answer:
$.56 per can; $.49 per can; 5 cans for $2.45
Step-by-step explanation:
If it were a dollar for two cans, it's pretty easy to figure out each can is 50 cents. So you use the same idea. if you have x cans for y dollars, if you divide both numbers by x you get the price of 1 can.
3 cans for 1.68 is 1 can for 1.68/3 = .56 so 56 cents
5 cans for 2.45 is 1 can for 2.45/5 = .49 so 49 cents.
You could use this trick dividing by the price and find how many cans you need to but to pay 1 dollar.
3 cans for 1.68 is 3/1.68 for 1 dollar or 1.786 cans for 1 dollar. Doesn't make a lot of sense since you can't but part of a can, but I wanted to show you how you could use the logic for other things.

Answers
Answer:
Therefore,
[tex]x=y= 4\sqrt{2}=5.6568\ units[/tex]
Step-by-step explanation:
Given:
Consider In Right Angle Triangle ABC
∠B = 90°
∠C = ∠A = 45°
AB = y
BC = x = adjacent side
AC = 8 = hypotenuse
To Find:
x = ?
y = ?
Solution:
In Right Angle Triangle ABC by Cosine Identity we have
[tex]\cos C = \dfrac{\textrm{side adjacent to angle C}}{Hypotenuse}\\[/tex]
substituting the above given values we get
[tex]\cos 45 = \dfrac{BC}{AC}=\dfrac{x}{8}[/tex]
[tex]\dfrac{1}{\sqrt{2} } =\dfrac{x}{8}\\\therefore x=\dfrac{8}{\sqrt{2} } \\Rationalizing\ we\ get\\\therefore x=\dfrac{8}{\sqrt{2}}\times \dfrac{\sqrt{2} }{\sqrt{2}}}\\\therefore x=4\sqrt{2}=4\times 1.4142=5.6568\ units[/tex]
As The triangle is 45 - 45 - 90
It is an Isosceles Right triangle
[tex]x=y[/tex]..... Isosceles Triangle property
[tex]\therefore y=4\sqrt{2}=4\times 1.4142=5.6568\ units[/tex]
Therefore,
[tex]x=y= 4\sqrt{2}=5.6568\ units[/tex]
Solve for w, x, y, z
x + 2y - z = 3
2x - y + z - w = -3
y + 2z - w = -7
x + 3y + 2z + 2w = 3
Answers
Answer:
x= 1; y= 0; z= -2 and w= 3.
Step-by-step explanation:
Given that,
1) x + 2y - z = 3
2) 2x - y + z - w = -3
3) y + 2z - w = -7
4) x + 3y + 2z + 2w = 3
now, from 1) z = x + 2y -3 →→(5)
from 2) w = 2x -y + z +3
⇒w = 2x -y + x + 2y -3 +3 (from (5))
w = 3x + y →→(6)
Now substitute (5) and (6) in 3), we get
y +2(x + 2y -3) - (3x + y) = -7
⇒ 4y - x = -1 →→→(7)
Now substitute (5) and (6) in 4), we get
x + 3y + 2(x + 2y -3) + 2(3x + y) = 3
⇒ 9x +9y = 9
⇒ x + y =1 →→→(8)
⇒ x= 1-y , substituting this in (7) gives 5y -1 = -1
⇒ y = 0 and x = 1
substituting these values in
(5) and (6) gives, z = -2 and w = 3
⇒ x= 1; y= 0; z= -2 and w= 3.
width of a rectangle is 7 meters greater than its length
Answers
Answer:
[tex]x^{2} +7x-170=0[/tex]
Step-by-step explanation:
Here is the complete question: The width of a rectangle is 7 meters greater than its length . If the area of the rectangle is 170 m², write the quadratic equation in standard form for the equation that would represent the area of the rectangle. Let x equal to the length of the rectangle.
Given: Width of rectangle is 7 meter greater than length
Length of rectangle is x.
Area of rectangle= 170 m²
Now as given, length is x meter and width is (x+7) meter
we know that, area of rectangle= [tex]length\times width[/tex]
∴ substitute the values to get correction equation.
⇒170= [tex]x\times (x+7)[/tex]
now distributing x into (x+7).
⇒ [tex]170= x^{2} +7x[/tex]
subtracting 170 both side.
[tex]x^{2} +7x-170=0[/tex]
∴ [tex]x^{2} +7x-170=0[/tex] is the quadratic equation in standard form for the equation that would represent the area of the rectangle.

Rajeev buys good worth Rs 6650.He gets a rebate of 6% on it.After getting the rebate, he pays sales tax @10%. Find the amount he will have to pay for the goods.
Answers
Rajeev will pay Rs 6876.10 for the goods.
Step-by-step explanation:
Given,
Worth of goods = Rs 6650
Rebate = 6%
Amount of rebate = 6% of worth of goods
Amount of rebate = [tex]\frac{6}{100}*6650=0.06*6650[/tex]
Amount of rebate = Rs 399
Amount after rebate = 6650 - 399 = Rs 6251
Sales tax = 10%
Amount of sales tax = 10% of amount after rebate
Amount of sales tax = [tex]\frac{10}{100}*6251=0.1*6251[/tex]
Amount of sales tax = Rs 625.10
Total amount of goods paid = Amount after rebate + sales tax
Total amount of goods paid = 6251+625.10 = Rs 6876.10
Rajeev will pay Rs 6876.10 for the goods.

Answers
Grant needs to ride at least 13.33 miles to male at least $ 15.00 a day
Solution:
Given that Grant has an agreement with Brian to rent the bike for $35.00 a night
He charges customers $3.75 for every mile he transports them
Grant needs to make at least $15.00 a day
To find: miles needed to ride
From given question, He charges customers $3.75 for every mile he transports them
So if he transports for "x" miles he would get,
[tex]\$ 3.75 \times x = \$ 3.75x[/tex]
So the profit he gets is $ 3.75 and initial cost invested to rent bike is $ 35. Also, Grant needs to make at least $15.00 a day
So we can frame a inequality as:
[tex]3.75x - 35 \geq 15\\\\3.75x\geq 35 + 15\\\\3.75x\geq 50\\\\x \geq 13.33[/tex]
So he needs to ride atleast 13.33 miles to male atleast $ 15.00 a day

A Six Flags theme park charges $30 for adults and $15 for kids. How many adult tickets and kid tickets were sold, if a total of 1,644 tickets were sold for a total of $11,250?
Answers
Answer:
The number of adult tickets sold is 894 and the number of kid tickets is 750.
Step-by-step explanation:
Given:
A Six Flags theme park charges $30 for adults and $15 for kids.
Total of 1,644 tickets were sold.
Total amount of tickets $11,250.
Now, to find the number of adult tickets and kid tickets.
Let the number of kid tickets be [tex]x.[/tex]
And the number of adult tickets be [tex]y.[/tex]
So, the total number of tickets:
[tex]x+y=1644.[/tex].....(1)
Solving the equation we get the value of [tex]x[/tex]:
[tex]x=1644-y.[/tex]
Now, the total amount of tickets of adult and kids:
[tex]15x+30y=11250.[/tex]
So, by putting the value of [tex]x[/tex] we get:
[tex]15(1644-y)+30y=11250[/tex]
[tex]24660-15y+30y=11250[/tex]
[tex]24660+15y=11250[/tex]
Subtracting both sides by 24660 we get:
[tex]15y=-13410[/tex]
Dividing both sides by -15 we get:
[tex]y=894[/tex]
Thus number of adult tickets = 894.
Now, putting the value of [tex]y[/tex] in equation (1):
[tex]x+894=1644[/tex]
On solving we get:
[tex]x=1644-894[/tex]
[tex]x=750.[/tex]
So. the number of kid tickets = 750.
Therefore, the number of adult tickets sold is 894 and the number of kid tickets is 750.

The legs of an iscosceles triangle have lengths 3x-1 and -x +27. The base has length 5x+1. What is the length of the base
Answers
Answer: 36
Step-by-step explanation:
The legs are given to be :
3x - 1 and -x + 27
The base = 5x + 1
One of the properties of an isosceles triangle is that two sides are equal , that is the two legs are equal. This means that
3x - 1 = - x + 27
3x + x = 27 + 1
4x = 28
x = 7
To calculate the length of the base, substitute x = 7 into the length of the base given , that is
Length of the base = 5(7) + 1
L = 35 + 1
L = 36

Answer:
The function through which given point passes is f(x) = 24 x - 12 .
Step-by-step explanation:
Given as :
The points are
[tex]x_1[/tex] , [tex]y_1[/tex] = 1 , 12
[tex]x_2[/tex] , [tex]y_2[/tex] = 2 , 36
now, slope of the line
Let The slope of line = m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Or, m = [tex]\frac{36 - 12}{2-1}[/tex]
Or, m = 24
So The slope of line = m = 24
Now, equation of line in point-slope form
y - [tex]y_1[/tex] = m × (x - [tex]x_1[/tex] )
Or, y - 12 = 24 × (x - 1 )
or, y - 12 = 24 x - 24
or, y = 24 x - 24 + 12
or, y = 24 x - 12
or , f(x) = 24 x - 12
So, The function through which given point passes is f(x) = 24 x - 12 . Answer

To solve for [tex]a[/tex]
In order to solve for [tex]a[/tex] we will try to isolate [tex]a[/tex] on one side of the equation.
Steps to isolate [tex]a[/tex].
1) Multiplying both sides by [tex]2[/tex] to remove fractions.
[tex]2\times s=2\times \frac{a+b+c}{2}[/tex]
[tex]2s=a+b+c[/tex]
2) Subtracting both sides by [tex]b[/tex]
[tex]2s-b=a+b-b+c[/tex]
[tex]2s-b=a+c[/tex]
3) Subtracting both sides by [tex]c[/tex]
[tex]2s-b-c=a+c-c[/tex]
[tex]2s-b-c=a[/tex]
Thus, we successfully isolated [tex]a[/tex] on one side. The formula for [tex]a[/tex] can be given as:

A sports shop has 84 employees. 25% of the employees work part-time. How many part-time employees does the sports shop have?
Answers
Answer:
The sports shop has 21 part-time employees.
Step-by-step explanation:
Solution:
What is 25% of 84?
.Y is 25% of 84
Equation: Y = P% * X
Solving our equation for Y
Y = P% * X
Y = 25% * 84
Converting percent to decimal:
p = 25%/100 = 0.25
Y = 0.25 * 84
Y = 21
Or another quicker way....
50% is half of the whole, and 25 is half of 50.
84/2/2
equals 21 too, I don't recommend to use it as row form.
The sports shop has 21 part-time employees, found by calculating 25% of 84.
The question asks how many part-time employees a sports shop with 84 employees has if 25% of them work part-time. To find the answer, we need to calculate 25% of 84 employees. The calculation is done as follows:
First, convert the percentage to a decimal by dividing it by 100: 25% = 0.25.
Then, multiply the total number of employees by this decimal: 84 times 0.25 = 21.
Therefore, the sports shop has 21 part-time employees.

Step-by-step explanation:
abs(x-5)=3
x-5=3, x-5=-3
x=3+5=8,
x=-3+5=2
Final answer:
option A. x=2, x=8
Explanation:
To solve the equation |x-5|=3, we need to consider both cases regarding the absolute value function. The absolute value of an expression is equal to 3 if the expression itself is 3 or -3. Therefore, we have two equations to solve:
x - 5 = 3x - 5 = -3Solving the first equation:
x = 3 + 5x = 8Solving the second equation:
x = -3 + 5x = 2Thus, the solutions for the equation |x-5|=3 are x=2 and x=8, which corresponds to option A.
A cube has a volume of 343 cubic cm. What is the area of the base
